whether or not the Width of the Wei-t is reduced, the "be'veling'cut-represented by the line 8- places the enter boundary o f'the trimmed margin Well inside the enter boundary of 'the'welt l so thatgwhen-the channel-flap 6 is subsequentlyclosed as illiis' trated in Fig. 5, it will project beyond the "outer boundary of the "beveled "margin of the prising the Welt and the channel-flapfl which outsole and Will lie in direct contact-With the lower face of the' Weltto' which it. will be secured'by an adhesive. Mereover,;the trim- :nii-ng out representedby the 'dottedline 9, be ing parallel to the upper face of the Welt,- V will remove a-ny'thic k' spots orfuzz" from" 1 the flesh side of the Welt and thus insure uniform thielmess of the two-bl mar in cortimargin may be subsequently trimmed more closely to the Welt-crease Without uncovering or encounteringfthe inter-posed beveledman gin "of the 'outsole. Inthis Way provision is made for a final edge-trimmingoperation by which a very thin marginal extension-0f the shoe-'bottem may be trimmed even more closely tothe welt creasewithout cutting into-the inclined portion of the closed channel-flap 61, into the beveledymargin of "the.

Referring toFigs; l, 2 and 3,-the present invention provides an improved cutterlinechanisni for reducing the thicln ess and the width of the margina'l'extensions of shoe botto nsin accordance with the foregoing expla nation. Th'is'mechan'isin cOniprises-a rotary toothed cutterhaving cutting teeth 46 projectihg outwardly from a hub 44 and taper- I ing tot'hin edges at their tips. The cutting I teeth are arrangedhetween twoconfronting Work-guiding finembersshown as circular shields 48 and 60, the shield 48 being ferined I and arranged to run in'the welt-crease of the 1 shoe as illustrated in Fig. 1, and the perimeter of the shield beingarranged. to run on the 'outsole at the junctien of the margin 5 Land the rootof the *in that figure.

quently closed asiillustrated -in Fig. 5, its edge will beapproximately,if not quite, flush'with the trimmedfiedge of the welt.' However, in certain aspects, the invention is not depend- --ent .upon', providing the cutting edges; .70,

since, even if the welt does project beyond the-channel-fiap after the-latter hasbeen closed, it will be subsequently: trimmed by another cutter mechanismwhich will be used Figs. 1 and 2 being well-known elements ofv edge-trimming machines heretofore in" use. As shown, the hub 44 ofthe cutter ismountedi on an" expansible, kerfed, steel thimbletO havinga flange 42 at itsrear end. This thinlble is internally tapered and is arranged upon a port1on'38 of liketa-por formed on arotary vf'lheshield 48, abuts against the forward end; of the hub 44 "ofthecutter and is provided with a circular shoulder that fits the bore :of the-hubto centralize theshield; A headed screw 52 extends through 'a hole in,

' the center of the shield 48 and into a screwthreaded socketin the center of the ShaftBQf 'As the screw 52 is screwed home -it forces the shield 48 against the hub 44 lof the cutter, the axial movement of the cutter being transmitted to the flange- 42 of the expansible thimble which is thereby, forced toward the larger end of the tapering portion 38 of the shaft. The thimble 4O is thus 'expanded tightly against the bore of the cutter. and, in addition, the-cutter is clamped by the shield 48 and the flange 4520f the thimble.

. The shield '60, which lies against the flat rear faces of the cutter teeth 46, is shown as a thin, flat ring of sheet metal, copper being suitable for this purpose. It, is backed or bracedby a stronger and. thicker ring 58 of steel, brass or other metal. Thisshield and its backing ring 58 are both carriedvby a sleeve 34 that surrounds the shaft 30' and is secured thereto by a set-screw 3 6, the sleeve being axially adjustable to provide for placing the shield against the backs of the teeth 46. A peripheral flange or shoulder 56 formed on-the sleeve 34 abuts the rear end of the backing ring 58 to maintain the shield 60 L in contact with the rear faces of the cutting teeth 46. The interior of the sleeve 34 is counterbored orjrelieved as indicated at 54 to clear the hub 44 of the cutter.

, In using the described cutter mechanism,

the operator manipulates a shoein substantially the same manner as for ordinary edget'rimming, that' is, by raising the shoe to press the welt and the margin of the outsole against'the under portion of the trimming shoe is arrestedfby the shield 480rthe shield be provided to V 60 orby'both, and by drawing the shoe edgewise pastthe cutter; If the'shoe isrocked while, it is being, drawn past the cutter, at least 'one of the shields will maintain control of the shoe to prevent the bevelingcut from extending too far toward therootof' the channel flap, but more commonly both of the] shields will share incontrolling the course of the trimming cut provided the location of the outsole channel has been proper= 1y located with respect to the welt-crease. However, no particular problenrarises with respect to properly locating the outsole channel if the later is outwith a rough-round- "111g and channeling machine after theoutisolehas been attached to a-shoe, since modern machines for that operation locate the outsole channel with sufficient accuracy to insure uniform and satisfactory results from the herein-described shanlnreducing cutter mechanism.
